Localization of sensor nodes is one of the key issues in Wireless Sensor Networks. It is a precondition for a variety of applications, as well as geographic clustering and routing....
This paper discusses several distributed poweraware routing protocols in wireless ad-hoc networks (especially sensor networks). We seek to optimize the lifetime of the network. We...
— In this paper, we address the network maintenance problem, in which we aim to maximize the lifetime of a sensor network by adding a set of relays to it. The network lifetime is...
—The demands for vehicular Internet access are proliferating. Access Points (APs) can be deployed along the roadside to provide wireless coverage and network access for mobile ve...
Abstract— Relaying and orthogonal frequency division multiple access (OFDMA) are the accepted technologies for emerging wireless communications standards. The activities in many ...
